Comparatively very little of that "humanity" corpus is coming from Shakespeare or Swift or Douglas Adams, much as we might prefer if it did.
But these days, when I write in that formal style, people sometimes say it sounds like AI. That has been a difficult and frustrating point for me.
I still find the subtle difference hard to understand.
Do the people who say you sound like AI give you any specifics?
Also, if you don't mind, what was your English education like? I understand that quite a few Americans work in South Korea as teachers but I have no details about how that manifests.
In Seoul, there are probably many teachers who mainly teach middle and high school students, but a lot of that is through private education rather than the public school system.
